A number of years ago, I interviewed a doctor assigned to "Merrill's Marauders," who operated behind Japanese lines in Burma. I thought he had some interesting observations. http://ww2thebigone.com/2016/03/27/merrills-marauders/
Thanks for this one too mojo1a. We have discussed Merrill's Marauders a few times on the forum. There is, as I'm sure you know a website in their honour, here: http://www.marauder.org
